RAILWAY BLOCK-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 329,092, dated October2'7, 1885 Application filed November 10, 1884. Serial No. 147,595.

To all whom it may concern.- 7

Be it known that I, ELI'H. SLAYBAUGH, a citizen of the United States,residing at Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Railway Block-Signals;and I do hereby declare that the following is a full, clear, and eXactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon, in which- Figure 1 is an isometrical view.Fig. 2 is a detached view. of slats and device for operat ing saidslats.

The present invention has relation to railway -signals designed tosignal a train at a telegraph-station and stop a train for orders or anyother purpose; and its nature consists in the different parts andcombination of parts, hereinafter described, and pointed out in theclaims.

Similar letters of reference indicate corresponding parts in thedrawings.

In the accompanying drawings, A represents the outside frame, which issubstantially of the form shown in Fig. 1, the top of which is providedwith the roof B, which may be of the form shown; or it may be of anyother desired form. The roof B and the bottom Gare attached to the frameA, as seen in the drawwas.

The upper portion of the frame A is provided with the signal slats orstrips D,which are substantially of the form shown in Fig. 1. As shown,five slats or strips are used; but any desired number may be used. Thesestrips or slats are attached to the frameA at their upper and lower endsin such a manner that they will easily turn. These slats are painteddifferent colors upon their opposite sides, such as a bright red uponone side and white upon the other. These slats. or strips D are made ofsheet iron or any other suitable material, and may be riveted orotherwise attached to the rods E, as seen in the drawings.

The top or upper ends of the rods E are provided with the cranks F, andthese cranks are attached bythe connectingbar G, so that motion will becommunicated to all of the slatsD by the movement of one of these slats,said slats being so arranged that they will turn (No model.)

half-way around without interfering with each other. The rod E, upon thecenter slat, D, is

provided at its bottom orlower end with the vided with a lens, K, whichare held in the frame J in any well-known manner. These lenses K aremade of uncolored glass.

Upon the inside of the frame J are located the glasses L, which aresubstantially of the form shown, and are held in the desired position bythe frame M. These glasses L are made of colored glass, the colorofwhich should correspond with the color upon one side of the slats orstrips D. The lower portion of the frame M is provided with the weightN,which is for the purpose of holding the glasses L in the positionshown in Fig. 1, and also assisting in bringing said glasses in thatposition after they have been turned so as to show a white light.

The frame M is attached to the shaft 0, as seen in Fig. 1, said shaftbeing attached to the support 1?, which is substantially of the formshown in the drawings, and is rigidly held in proper position bysuitable clamping-bolts or rivets.

The upper portion of the frame M is provided with the lever or arm Q,which extends above the shaft 0, as seen in Fig. 1, and is for thepurpose of attaching the operating-rod R.

Only one of the glasses and connecting partsis shown in full, the otherbeing broken away or sectioned, as appears in the drawings; but both areconstructed and operate alike, although independent of each other.

In use the signal proper is placed at the required height upon a post,standard, or' other frame-work, and the operating-rods R extend to thetable of the operator. When the telegraphoffice is located above theground floor, and when the office is located upon the ground floor, thesignal may be operated by means of Cords.

It will be seen that by my peculiar arrangelocated the frame J, I

mentI am enabled to signal a train from either direction, and at thesame time leave the signal in its normal condition upon one side, aseach glass L operates independently of the other. It will also be seenthat on double-track roads I am enabled to signal a train coming fromone direction and let a train pass coming from the opposite direction,if it is not desired to stop the train.

During the night a lamp or other light is placed in the frame or box J.

The operations of my invention are as follows: In case it is desired tosignal a train, the colored glass is placed in the position shown inFig. l by movement of rod R,which movement at the same time turns theslats D,through the instrumentality of the rod 0, the segment I, thepinion H, the cranks F, and the conmeeting-rod G.

The relative arrangement and relation of segment I, pinion'H, and crankQ is such, as shown,- that by moving rod R the slats D will makeone-half a revolution while the glass L is making one-quarter of arevolution.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is I V 1. The combination of frame A,having on opposite sides pivoted slats D, with frame J within frame A;and containing on opposite sides swinging glasses L, connected with saidslats to move therewith, substantially as described.

2. In a signal, the combination of a series of pivoted slats, a swinginglens or glass connected to said slats to move with them, and a leverfor-moving said glass, substantially as described.

3. In a signal, the combination of a series of pivoted slats connectedtogether and a pinion connected with one of said slats, a shaft having asegment engaging with said pinion, a glass connected to said shaft tomove therewith, and a lever for turning said shaft, substantially asdescribed.

4. The shaft 0, provided with the segment I, in combination with thepinion H and the slats O, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
